CLOCK-CHIME.

SPECIFICATION forming part of Letters Patent No. 710,084, datedSeptember 30, 1902.

Application filed July 22, 1901. Serial No. 69,323. (No model.)

To (all w/tom/ it 71mg/ concern.'

Be itknown that I, GEORGE M. STEVENS, of Cambridge, in the county ofMiddlesex and State of Massachusetts, have invented a new and usefulImprovement in Chime-Ringing Apparatus, of which the following, taken inconnection with the accompanying drawings, is a specification.

My invention relates to a device that will at certain predeterminedtimes cause a peal or a succession of peals to be sounded upon a set oftuned bells; and it consistsin peculiarly constructed and combinedmechanisms adapted to operate upon a chime of bells for the purpose ofproducing musical pcals, especially for the purpose of cadencingtheAngelus, and maybe best understood by reference to the specification andaccompanying drawings.

The illustration consists of the followingdescribed tigures, of Which-Figure 1 illustrates in elevation the entire apparatus. Fig. 2 is aview, partly in plan and partly diagrammatical. Fig. 8 is an elevationof the controller, on a larger scale than the one shown in Fig. 1. Aportion is represented as cut away to show working parts more clearly.

In the general View of my apparatus, Fig. 1, C represents a clock, whichmaybe of any kind that will ad mit of being provided with electricmake-and-lneak contact-points adapted at certain fixed times to close oropen an electric circuit, and th ns start a clock-train.

K indicates the motor-train which operates the electric-circuit-closingdisks that control the bell-striking machines A. Only one of the Saidbell-striking machines is shown in the drawings; but, in fact, there areas many of these machines as there are bells. The bellstriking machinesare operated byu Weights W, operating through cords and piuldescribed inpatent granted to me July G, 1897, No. 585,718; but any striking-machinemay be used.

The motor-train that gives motion to the circuit-closing disk is shownin Fig. 3 and consists of a train of wheelsdriven by a spring or weight.The train of wheels gives motion to the shaft F, upon which are mountedfour (in this case) disks D D' D2 D3, each having` projecting points d,Fig. which in succession act upon a spring condnoter-plate, as j),mounted upon one of the insulator-blocks I P' I2 P3, and force ittomalte an electric connection with another conductor-plate, asf, (seeFigs. 3 and 2,) thus establishing an electric circuit through one of thebell-strikintor machines A.

The let-off device for the above motor-train consists ot' aneleetromagnet M, energized by the generator G. An armature M operates alever L2 L4 L, which is pivoted at L@ The two branches of the lever Land L4 act together; but one, L, operates in connection with the wheel Fand the other, L, in connection with the wheel N. The branch L has a pinl, which rests against the edge of the riinon the wheel F. The edge ofthe rim F is cut into, as shown at F2, (and at other points, ifdesired,) so that at this point the pin L may be forced by the s rinO Sinward as shown in FO. 3. In this position the hooked arm L4 of thelever L LA1 engages with a pin N on the wheel N, and thus stops andholds it. To start the motor-train, the magnet IWI has to be energized,so as to draw the armature M'. This action will operate the lever L andits arms L L4, thus removing the hook from the pin N' and allowing thewheels to rotate. As the wheel F' rotates it will cause the rim F2 tomove, so that the notch F3 will no longer be in position for the pin Z.on the lever L to drop into it, the said pin being held by the full partof the rim F2, so that the hook on the end of the arm L4 cannot engagewith the pin N' and thus stop its rotation; but as soon as the wheel Fin its.rotation brings one of the notches in the rim F2 opposite to thepin l then the lever and its arm L4 will be drawn inward by the springS, and the hook at the end of the arm L4 will engage with the pin N andstop the train and hold it until the magnet is again energized. Otherstopping devices may be used.

In Fig. 2 a series of switch-buttons T T T2 T3 are shown. These afford ameans for ringing any one or all of the bells independently of the clockand the clock-train.

The operation of my apparatus may be explained as follows: The clock andthe motortrain are both Wound up. At the time for ringing the bells anelectric connection will be made by the clock through the Wires c c'(see Figs. 2 and 3) and the electromagnet M will be energized, and, asalready explained, the clock-train Will start, giving motion to theelectric-circuit-closing disks D D' D2 D2. The electric circuit for thedisk D (which, acting through the bell-striking machine, sounds the bellB) consists of the conductorplate p, Wire b, Fig. 2, to thestriking-machine of bell B, Wires do and c to generator G, then by Wirefback to conductor-platep. The circuit for bell B is Wires b cl e,generator G, wire f; for the bell B2, wires b2 d2 e, generator G, Wiref2; for the bell B3, wire b2 d3 e, generator G, Wirefs. Theswitch-button circuits are, for bell B, button T, wires a" b tostriking-machine, Wires d c to generator G, Wiresft; for bell B', buttonT', wires r' b' to striking-machine, wires d e to generator, wiresf; forbell B2, Wires r2 b2 to machine, wires d2 c to generator G, Wires f t2;for bell B3, Wires r2 b3 to machine, Wires d3 c to generator, Wires ft3.

I have shown and described in this application a system ofswitch-buttons by means of which the bells may be rung directly by theoperator; but I do not claim the same, as that will be the subject ofanother application.

I claim- A chime-ringing apparatus, comprising a chime ot' bells, eachhaving a hammer adapted to strike its bell; mechanisms for operatingsaid hammers; electrical circuits including an electrical generator andmake-and-break disks adapted to cause said mechanisms to operate; aseries of make-and-break disks having contact-points arranged to causethe said mechanisms to strike the bells in musical order; a motor-trainfor actuating the said make-and-break disks; a mechanism for startingsaid motor-train; a clock-movement for timing the operation of saidstarting mechanism, all adapted to operate together, substantially asand for the purpose set forth.

In` testimony whereof I have signed my name to this specification, inthe presence of two subscribing Witnesses, on this 19th day of July, A.D. 1901.

GEORGE M. STEVENS.
